There are a few different styles of retaining clips in hydraulic lifters my pic was just an example. What you have sure looks like a hydraulic to me but the pics are not clear enough to tell for sure. Don’t assume, be 100% sure of what you have because how you adjust them will matter. And I could not agree more with @Newbomb Turk use what you have just make it right. Even if you have to buy shafts.
